SpringBoot 控制枱秒變炫彩特效，秀翻同事指南！ - Stories Detail

一、自定義 Spring Boot 啓動橫幅 banner.txt

1、什麼是 banner.txt？

當你啓動 Spring Boot 應用時，控制枱會打印出一個默認的 Spring Boot Banner（比如啓動 LOGO）。這個內容來自 resources 目錄下的 banner.txt 文件。你可以通過這個文件自定義你想展示的 ASCII 圖案、版本號、提示文字等。

2、創建或修改 banner.txt

2.1、文件位置：

在你的 Spring Boot 項目中，進入 src/main/resources 目錄下，新建或編輯：

src/main/resources/banner.txt

2.2. 內容示例（純色風格 + 啓動信息）：

===========================================
==         AbsWeb 啓動成功！ 🚀         ==
==         端口：${server.port}               ==
==         環境：${spring.profiles.active}       ==
==         時間：${date}              ==
===========================================

你可以使用 Spring Boot 提供的一些佔位符變量：

佔位符 描述
${application.version} 項目的 MANIFEST.MF 版本
${application.formatted-version} 格式化版本號
${spring-boot.version} Spring Boot 版本
${server.port} 當前端口號
${spring.profiles.active} 當前激活的配置環境
${date} 啓動時間
${AnsiColor.NAME} 控制枱顏色（如 GREEN、RED）

3、加點顏色和風格（可選）

Spring Boot 支持 ANSI 顏色，在支持的終端中會顯示彩色效果：

${AnsiColor.BRIGHT_CYAN}
===========================================
==         AbsWeb 啓動成功！ 🚀         ==
==         端口：${server.port}               ==
==         環境：${spring.profiles.active}       ==
==         時間：${date}              ==
===========================================
${AnsiColor.DEFAULT}

4、啓動測試

啓動項目時，你會看到類似輸出：

===========================================
==         AbsWeb 啓動成功！ 🚀         ==
==         端口：8082                     ==
==         環境：test                     ==
==         時間：2025-06-13 16:52:10      ==
===========================================

提供幾個網站可以自己去生成圖案:

二、進階方式：關閉默認 Banner，自定義 Java 啓動內容

1、禁用 Spring Boot 的默認 banner：

在你的配置文件（如 application.yml 或 application.properties）中添加：

yml 文件：

spring:
  main:
    banner-mode: "off"

properties 文件：

spring.main.banner-mode=off

2、自定義啓動打印代碼

在主啓動類中添加一個打印方法，利用 ANSI 轉義碼輸出彩色字符：

public class AbsWebApplication {
 
    private static final String RESET = "\u001B[0m";
    private static final String CYAN = "\u001B[36m";
    private static final String BLUE = "\u001B[34m";
    private static final String PURPLE = "\u001B[35m";
    private static final String WHITE = "\u001B[37m";

    public static void main(String[] args) {
        SpringApplication.run(AbsWebApplication.class, args);
        printBanner();
    }

    private static void printBanner() {
        System.out.println();
        System.out.println(CYAN + "╔════════════════════════════════════════════╗" + RESET);
        System.out.println(CYAN + "║" + BLUE + "  █████╗ ██████╗ ███████╗ ██████╗ ██╗  ██╗  " + CYAN + "║" + RESET);
        System.out.println(CYAN + "║" + BLUE + " ██╔══██╗██╔══██╗██╔════╝██╔═══██╗██║ ██╔╝  " + CYAN + "║" + RESET);
        System.out.println(CYAN + "║" + BLUE + " ███████║██████╔╝█████╗  ██║   ██║█████╔╝   " + CYAN + "║" + RESET);
        System.out.println(CYAN + "║" + BLUE + " ██╔══██║██╔═══╝ ██╔══╝  ██║   ██║██╔═██╗   " + CYAN + "║" + RESET);
        System.out.println(CYAN + "║" + BLUE + " ██║  ██║██║     ███████╗╚██████╔╝██║  ██╗  " + CYAN + "║" + RESET);
        System.out.println(CYAN + "║" + BLUE + " ╚═╝  ╚═╝╚═╝     ╚══════╝ ╚═════╝ ╚═╝  ╚═╝  " + CYAN + "║" + RESET);
        System.out.println(CYAN + "║                                            ║" + RESET);
        System.out.println(CYAN + "║ " + WHITE + ">>> AbsWeb Application 啓動成功 <<<" + CYAN + "           ║" + RESET);
        System.out.println(CYAN + "║ " + PURPLE + "版本: v2.6.13  時間: " + WHITE + java.time.LocalTime.now() + CYAN + "        ║" + RESET);
        System.out.println(CYAN + "╚════════════════════════════════════════════╝" + RESET);
        System.out.println();
    }
}

輸出結果如下：

下面多提供幾個圖案：

public class AbsWebApplication {
 
    private static final String RESET = "\u001B[0m";
    private static final String CYAN = "\u001B[36m";
    private static final String MAGENTA = "\u001B[35m";
    private static final String BLUE = "\u001B[34m";
    private static final String YELLOW = "\u001B[33m";

    public static void main(String[] args) {
        SpringApplication.run(AbsWebApplication.class, args);
        printBanner();
    }

    private static void printBanner() {
        System.out.println();
        System.out.println(MAGENTA + "╔══════════════════════════════════════════════════╗" + RESET);
        System.out.println(MAGENTA + "║                                                  ║" + RESET);
        System.out.println(MAGENTA + "║   " + CYAN + "██████╗  █████╗ ██████╗  ██████╗ ██╗      ██╗     " + MAGENTA + "║" + RESET);
        System.out.println(MAGENTA + "║   " + CYAN + "██╔══██╗██╔══██╗██╔══██╗██╔═══██╗██║     ██╔╝     " + MAGENTA + "║" + RESET);
        System.out.println(MAGENTA + "║   " + BLUE + "██████╔╝███████║██████╔╝██║   ██║██║    ██╔╝      " + MAGENTA + "║" + RESET);
        System.out.println(MAGENTA + "║   " + BLUE + "██╔═══╝ ██╔══██║██╔═══╝ ██║   ██║██║    ╚═╝       " + MAGENTA + "║" + RESET);
        System.out.println(MAGENTA + "║   " + YELLOW + "██║     ██║  ██║██║     ╚██████╔╝███████╗         " + MAGENTA + "║" + RESET);
        System.out.println(MAGENTA + "║   " + YELLOW + "╚═╝     ╚═╝  ╚═╝╚═╝      ╚═════╝ ╚══════╝         " + MAGENTA + "║" + RESET);
        System.out.println(MAGENTA + "║                                                  ║" + RESET);
        System.out.println(MAGENTA + "║   " + CYAN + ">>> AbsWeb Application 啓動成功 <<<               " + MAGENTA + "║" + RESET);
        System.out.println(MAGENTA + "║   " + CYAN + "版本: v2.6.13    時間: " + java.time.LocalTime.now() + "                 " + MAGENTA + "║" + RESET);
        System.out.println(MAGENTA + "║                                                  ║" + RESET);
        System.out.println(MAGENTA + "╚══════════════════════════════════════════════════╝" + RESET);
        System.out.println();
    }
}
public class AbsWebApplication {

    private static final String RESET = "\u001B[0m";
    private static final String RED = "\u001B[31m";
    private static final String GREEN = "\u001B[32m";
    private static final String BLUE = "\u001B[34m";
    private static final String PURPLE = "\u001B[35m";
    private static final String YELLOW = "\u001B[33m";

    public static void main(String[] args) {
        SpringApplication.run(AbsWebApplication.class, args);
        printBanner();
    }

    private static void printBanner() {
        System.out.println();
        System.out.println(PURPLE + "╔══════════════════════════╗" + RESET);
        System.out.println(PURPLE + "║ " + RED + "▂▃▅▇█ AbsWeb啓動成功 █▇▅▃▂" + PURPLE + " ║" + RESET);
        System.out.println(PURPLE + "║ " + GREEN + "Version: v2.6.13" + "                      " + PURPLE + "║" + RESET);
        System.out.println(PURPLE + "║ " + BLUE + "Time: " + java.time.LocalTime.now() + "         " + PURPLE + "║" + RESET);
        System.out.println(PURPLE + "╚══════════════════════════╝" + RESET);
        System.out.println();
    }
}

自己也可以讓 AI 去生成。

三、實現啓動成功後的彩色提示

public class AbsWebApplication {
    public static void main(String[] args) {
        SpringApplication.run(AbsWebApplication.class, args);
        printStartupMessage();
    }

   private static void printStartupMessage() {
        String reset = "\u001B[0m";
        String red = "\u001B[31m";
        String yellow = "\u001B[33m";
        String green = "\u001B[32m";
        String cyan = "\u001B[36m";
        String magenta = "\u001B[35m";
        String blue = "\u001B[34m";
        System.out.println(cyan + "    (\\_/)  " + reset);
        System.out.println(cyan + "    ( •_•)  " + reset + red + "  AbsWebApplication 啓動成功!" + reset);
        System.out.println(cyan + "  / >🍪  " + reset + yellow + "  祝你今天工作順利，項目無BUG~" + reset);
        System.out.println();
        System.out.println(magenta + "  ┏━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━┓" + reset);
        System.out.println(magenta + "  ┃      🎉 歡迎使用 AbsWeb！🎉     ┃" + reset);
        System.out.println(magenta + "  ┗━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━┛" + reset);
    }
}

啓動後示例：

下面提供幾個示例：
546a70ff1b280835262fff4d6c557245.png

放進方法進行替換就行了。

final String PURPLE = "\u001B[35m";
final String RED = "\u001B[31m";
final String RESET = "\u001B[0m";

System.out.println(PURPLE + "   .----.  .----. " + RESET);
System.out.println(PURPLE + "  /      \\/      \\" + RESET);
System.out.println(RED + " |  (•)   (•)  | " + RESET);
System.out.println(PURPLE + " |     <       | " + RESET);
System.out.println(PURPLE + "  \\   --'    /  " + RESET);
System.out.println(PURPLE + "   `--------'    " + RESET);
System.out.println(RED + "    AbsWeb 已啓動!" + RESET);
public static void printTechWave() {
    final String RESET = "\u001B[0m";
    final String BLUE = "\u001B[34m";
    final String CYAN = "\u001B[36m";
    final String PURPLE = "\u001B[35m";
    final String WHITE = "\u001B[37m";

    System.out.println(CYAN + "╔════════════════════════════════════════════╗" + RESET);
    System.out.println(CYAN + "║" + BLUE + "    ██╗   ██╗████████╗██╗   ██╗███████╗        " + CYAN + "║" + RESET);
    System.out.println(CYAN + "║" + BLUE + "    ██║   ██║╚══██╔══╝██║   ██║██╔════╝        " + CYAN + "║" + RESET);
    System.out.println(CYAN + "║" + BLUE + "    ██║   ██║   ██║   ██║   ██║█████╗          " + CYAN + "║" + RESET);
    System.out.println(CYAN + "║" + BLUE + "    ██║   ██║   ██║   ██║   ██║██╔══╝          " + CYAN + "║" + RESET);
    System.out.println(CYAN + "║" + BLUE + "    ╚██████╔╝   ██║   ╚██████╔╝███████╗        " + CYAN + "║" + RESET);
    System.out.println(CYAN + "║" + BLUE + "     ╚═════╝    ╚═╝    ╚═════╝ ╚══════╝        " + CYAN + "║" + RESET);
    System.out.println(CYAN + "║                                            ║" + RESET);
    System.out.println(PURPLE + "║    🚀 AbsWeb Application 啓動成功！🚀       ║" + RESET);
    System.out.println(PURPLE + "║   Version: v2.6.13    " + WHITE + "啓動時間: " + java.time.LocalTime.now() + "   " + PURPLE + " ║" + RESET);
    System.out.println(CYAN + "╚════════════════════════════════════════════╝" + RESET);
